Imishini yokubona intuthu ithola umlilo ngentuthu. Uma ungaboni amalangabi noma unuka intuthu, umtshina wentuthu usuwazi. Isebenza ngokungami, izinsuku ezingama-365 ngonyaka, amahora angama-24 ngosuku, ngaphandle kokuphazamiseka. Izitholi zentuthu zingahlukaniswa cishe zibe yisigaba sokuqala, isigaba sokukhula, kanye nesigaba sokucisha ukuncipha ngesikhathi senqubo yokuthuthukisa umlilo. Ngakho-ke, ingabe uyawazi umgomo wokusebenza komtshina wentuthu ovimbe ukwenzeka komlilo kithi? Umhleli uzokuphendulela.
Umsebenzi womshini wokuthungatha intuthu ukuthumela ngokuzenzakalelayo isignali ye-alamu yomlilo phakathi nesigaba sokuqala sokukhiqiza intuthu, ukuze kucishwe umlilo ngaphambi kokuba ube yinhlekelele. Umgomo wokusebenza kwezitholi zomusi:
1. Ukuvimbela umlilo kufinyelelwa ngokuqapha ukugcwala kwentuthu. Ukuzwa intuthu ye-ionic kusetshenziswa ngaphakathi komtshina wentuthu, okuwubuchwepheshe obuthuthukisiwe, inzwa ezinzile nethembekile. Isetshenziswa kakhulu ezinhlelweni ezihlukahlukene ze-alamu yomlilo, futhi ukusebenza kwayo kuphakeme kakhulu kunaleyo yama-alamu omlilo ohlobo lwegesi azwelayo.
2. Umtshina wentuthu unomthombo okhipha imisebe we-americium 241 ngaphakathi kwamagumbi e-ionization angaphakathi nangaphandle. Ama-ion amahle kanye nama-negative akhiqizwa i-ionization aya kuma-electrode amahle futhi angalungile ngaphansi kwesenzo senkambu kagesi. Ngaphansi kwezimo ezijwayelekile, amandla amanje kanye ne-voltage yamagumbi e-ionization angaphakathi nangaphandle azinzile. Uma intuthu iphuma ekamelweni langaphandle le-ionization, iphazamisa ukunyakaza okuvamile kwezinhlayiya ezikhokhiswayo, i-current and voltage izoshintsha, iphazamise ibhalansi phakathi kwamakamelo angaphakathi nangaphandle ionization. Ngakho-ke, isidlulisi esingenantambo sithumela isignali ye-alamu engenantambo ukuze yazise umsingathi owamukela kude futhi idlulisele ulwazi lwe-alamu.
3. Imishini yokubona intuthu kagesi nayo iyimishini yokubona amaphuzu. Isimiso sokusebenza semishini yokubona intuthu ye-photoelectric ukusebenzisa impahla eyisisekelo ukuthi intuthu ekhiqizwe ngesikhathi somlilo ingashintsha izici zokusakaza zokukhanya. Ngokusekelwe ekumunceni nasekuhlakazweni kokukhanya yizinhlayiya zentuthu. Imishini yokubona intuthu yezithombe ihlukaniswe yaba izinhlobo ezimbili: uhlobo olumnyama kanye nohlobo lwe-astigmatic. Ngokwezindlela ezihlukene zokufinyelela kanye nezindlela zokuphakela amandla ebhethri, ingahlukaniswa ngezitholi zentuthu zenethiwekhi, izitholi zentuthu ezizimele, nezitholi zentuthu ezingenantambo.
